2008 winnebago access slide not working??

Ok everyone let me update you.... Tonight I went out and manually cranked slide out. I was able to get the touch pad to go into manual mode and the slides came in. That immediately told me I have power to the slide. However the slide would not go out still flashed parking brake light. So I manually cranked slide out again. Running out of ideas I decided to push parking brake all the way down to the floor. What do you know the slide came in like it should, and now goes out like it should. I had ruled the parking brake out do to the rear slide working. How ever the parking brake sends two separate signals to two separate controllers. I could make it not work by not pushing brake all the way down. I never would have guessed that the brake would need pushed all the way down but it worked. Thanks to everyone who offered suggestions and happy camping!
